![]() Avoid recomputing the Ethernet header location and instead just use the pointer provided by skb->data. The problem with using eth_hdr is that the compiler wasn't smart enough to realize that skb->head + skb->mac_header was the same thing as skb->data before it added ETH_HLEN. By just caching it off before calling skb_pull_inline we can avoid a few unnecessary instructions. Signed-off-by: Alexander Duyck <alexander.h.duyck@redhat.com> Signed-off-by: David S.
